GREEN BUILDING:
Past, Present and Future

2. It is an attempt to minimize each person’s impact on the world.
SUSTAINABILITY:
Thinking holistically about how everything you do affects everything around you.
It is an attempt to minimize each person’s impact on the world.

3. GREEN BUILDING:
Increase the efficiency of how buildings & their sites use energy, water and materials

4. GREEN BUILDING:
Reduce building impacts of human health and the environment, through better siting, design, construction, operation, and maintenance throughout life cycle

17. EARLY 1900’S Built in Conjunction with Railway Lines
Situated Around Existing Towns & Cities
Increase in Transportation = More Building Materials
More Affordable Housing
Detached Garage for New Autos
Underground Sewage Pipes = Healthier
No Servants, Smaller Homes

18. DEEP PORCHES INTEGRAL IN PASSIVE SOLAR DESIGN
EARLY 1900’S
DEEP PORCHES INTEGRAL IN PASSIVE SOLAR DESIGN

19. 1930’s New Technologies Transforms Urban Landscape
Air Conditioning, Structural Steel, Reflective Glass
Reliance on Non-Renewable Energy
Regressive Movement in Architecture
Design Began to Ignore Climate Issues & Their Effects
Loss of Builder-Architects = Lack Holistic Approach
Easy to Alter Internal Environments, Rather than Adapt

20. WILLIAM MCDONOUGH
“Most conventional practitioners of modern design and construction find it easier to make buildings as if nature and place did not exist. In Rangoon or Racine, their work is the same.”

21. FACILITATING CHANGE 1977: Department of Energy Established to Address
Energy Usage & Conservation
1987: UN Commission Provides First Definition of
Sustainable Development- “meets the needs of the present without compromising the ability of future generations to meet their own needs”
1990: Austin Establishes 1st Green Buiding Program
2000: Increasing Number of Municipalities & Corps
Begin to Demand Internal Green Bldg Standards

23. GREEN BUILDING TODAY Minimizes Home’s Footprint on Earth
Integrated Design
Uses Less Energy & Water
Durable/Low-Maintenance
Healthier
Reduced Greenhouse Emissions
Recycled Content Materials/Renewables

25. DESIGN PRINCIPLES Building Should be Elongated on an East-West Axis
to Control Sun’s Intrusion
Light Color, Highly Reflective Exterior Products
Utilize Natural Breezes and Shading
Work with, Not Against, Natural Setting
